ABSTRACT:
A printer having a daisy type-wheel or the like comprises a carrier longitudinally movable along a platen and a carriage detachably and pivotally mounted on the carrier. Mounted on the carriage are a ribbon cartridge, the type-wheel, a hammer assembly and a magnet assembly for actuating the hammer assembly. The design of the printer permits easy and accurate positioning and adjustment of constituents of the carriage, easy and accurate attachment of the carriage to the carrier, and easy tilting of the carriage for replacement of the type-wheel. Shifting of the type-wheel is achieved rapidly and with the low vibration. The ribbon cartridge may be moved from a non-printing to a printing position easily, with low vibration and with little generation of noise. The U-shaped ribbon cartridge includes an engaging member extending from a front leg of the cartridge toward the inside of the U-shape. The engaging member cooperates with a stopper member and the engaging lugs of the cartridge cooperate with a cartridge receiving apparatus of the carriage, so as to rotatably mount the cartridge on the carriage. The stopper member of the carriage provides a means for cooperating with the engaging member of the cartridge to govern the pivoting of the cartridge into and from the printing position.
